When you click the flag, the game will start, so here's how it works: Red: Left and Right arrow keys, keep the ball from rolling of the screen. Blue: Up and Down arrow keys, rally the ball don't let it get past you. Yellow: Wasd, grab the coins to replenish your timer, don't hit zero. Purple: Space, hold space to stop the triangle from falling, easy as that. Orange: Q and E, slide the bar to avoid the falling arrows. Green: U, hold you when the timer hits zero to replenish it, don't forget about it.
This is a recreation of the flash game with the same name. Left Number is your score, right is the World Record. Good luck!
